Embodiment
The present invention adopts the user knowledge base real time correlation, therefore can ensure the real-time of knowledge base the inside knowledge.
Key of the present invention is machine learning and the intelligent combination of entity personal set gunz, makes up the defect that traditional independent machine learning exists.Accompanying drawing 1 is shown in by whole scheme model, and the foundation of user knowledge base and renewal are bases of the present invention, and the cooperation of multi-user's knowledge base is the key of quick solution challenge.
The present invention relate generally to that problem pretreatment module, conflict co-ordination principle storehouse, subproblem are decomposed storehouse, result is synthetic with the enforcement of evaluation module with cooperate.Key step is as follows:
The first step: utilize problem that pretreatment module submits the user to carry out pre-service according to problem complexity etc., formation problem tree, and be distributed on the problem communal space.
Second step: the problem of the problem communal space is decomposed problem by subproblem decomposition rule storehouse, and in succession is distributed to sub-knowledge base, makes the sub-knowledge base can parallel processing.
The 3rd step: sub-knowledge base is submitted to the problem communal space by result after retrieving and processing subproblem.If have conflict rule between each knowledge base, be beneficial to the conflict rule storehouse and coordinate to solve.
The 4th step: the formation answer is integrated in each subproblem answer that communal space the inside is obtained, and checks on one's answers and estimated.
The 5th step: if, when the 4th step evaluation answer does not meet standard given in advance, will carry out artificial treatment and knowledge base will be fed back, thus the knowledge in the storehouse of refreshing one's knowledge.
The 6th step: the problem answers obtained is submitted to the user.
When problem is fairly simple, can directly utilize outside pointer to carry out calling knowledge base, even do not need the decomposition rule storehouse to carry out PROBLEM DECOMPOSITION, when problem is more complicated, can utilize above-mentioned model mechanism to decompose and solve problem, each knowledge base means a knowledge source, contain the required special knowledge of specific area problem solving, can solve relatively complete a, subproblem independently.
When challenge is carried out to resolution process, usually need according to the complexity of problem itself decomposed, dimensionality reduction operation etc., and that subproblem forms relativity according to the primary and secondary of problem attribute is lower, the problem tree node that independence is higher.Can carry out the traversal of ad hoc rules to the problem tree, thereby guarantee can not leave over subproblem, and carry out the integration of result according to the contrary rule of traversal rule after subproblem is processed fully, can guarantee like this rationality and the correctness of result.
Leaf node in the problem tree is all some relatively independent subproblems, give weights for each leaf node, each leaf node is from a task chain of acquisition in subproblem decomposition rule storehouse, task chain points to corresponding knowledge base, if can utilize outside pointer to be called when knowledge base need to be called other relevant knowledge storehouses, and find that in the process of dealing with problems some knowledge base calls the frequent outside pointer that can its outside pointer is set to fix, facilitate each knowledge base to call.
At this piece of knowledge base, in order to obtain in time newer knowledge, we adopt real-time update mechanism, avoid the hysteresis quality of knowledge base knowledge as far as possible, for those common sense knowledge storehouses, according to evaluation module, feed back to knowledge base, make knowledge base knowledge follow up the epoch in time.Knowledge related question for user knowledge base can adopt cluster association according to actual conditions, Attribute Association etc.
Result is synthetic is mainly the subproblem knowledge base to be solved to the answer of submitting to carry out Knowledge Integration with evaluation module, and is estimated according to evaluation mechanism.The evaluation of knowledge base can adopt the qualitative and quantitative mode to be estimated, and wherein qualitative analysis can be taked as expert survey etc.Quantitative test can be taked the multiattribute assessment method.Wherein evaluation index can be selected such as the knowledge base content quality according to actual conditions, Knowledge Base Techniques performance, the ease for use of knowledge base, knowledge base content quantity, the rate of people logging in of knowledge base and the ratio of error of knowledge base etc.
Below enumerate a simple application scenarios: the user has submitted the computer cisco unity malfunction problem of a complexity to, at first problem is carried out to pre-service and obtain the problem tree, his subproblem is likely that software causes that operating system can not normally move, the computer malfunction problem that hardware causes.But such subproblem is still too complicated, need to further decompose, until can not decompose again.Cause that such as decomposing the computer blue screen computer can not normally move, we decompose computer blue screen code subproblem, then the emphasis retrieval is about the knowledge base of computer blue screen code, and submit a question and obtain relevant information until search the answer of blue screen code knowledge base according to the user, and jointly submit to the answer that other knowledge bases obtain, finally according to the weights of subproblem answer, arrange to integrate and give evaluation module, evaluation module provides best a series of answers according to the evaluation index customized, next be exactly that evaluation system feedback and user obtain the feedback obtained according to actual solution situation after answer, it should be noted that the user feedback rank is higher than the priority of evaluation system, but in order to prevent the feedback of malicious user, we need to arrange certain authority to user feedback, and authority give situation and the contribution degree that can in the past use according to the user, the attributes such as specialty degree carry out giving different authorities after comprehensive evaluation.So both can increase user's enthusiasm, and also can utilize cluster wisdom to make up simple machine learning, the deficiency of reasoning.
